Call backs from screening mammograms create much anxiety yet, are common. Throughout the United States 6 – 12 women out of 100 who have a screening mammogram will be asked to return for additional evaluation. Most of these additional evaluations include special mammogram views and/or an ultrasound examination. Very often, these extra imaging steps provide an explanation of the original finding. A small percentage show findings that do, however, require a biopsy to know if an abnormality is cancer or a benign entity. Women are usually told the results of the additional call back imaging studies on the same day that they are performed.
3D mammography, breast digital tomosynthesis, is a new type of mammogram that has been shown to decrease call backs from screening mammograms. This technology is becoming more widespread and will help decrease the chances that you will be called back from a screening mammogram.
Screening breast ultrasound is another technology that is being more widely used as a supplement to screening mammography in women with dense breasts; this may also help decrease the call backs from screening mammography.
